133 +Broadcom introduced new bus as replacement for older SSB. It is based on AMBA,
134 +however from programming point of view there is nothing AMBA specific we use.
135 +
136 +Standard AMBA drivers are platform specific, have hardcoded addresses and use
137 +AMBA standard fields like CID and PID.
138 +
139 +In case of Broadcom's cards every device consists of:
140 +1) Broadcom specific AMBA device. It is put on AMBA bus, but can not be treated
141 + as standard AMBA device. Reading it's CID or PID can cause machine lockup.
142 +2) AMBA standard devices called ports or wrappers. They have CIDs (AMBA_CID)
143 + and PIDs (0x103BB369), but we do not use that info for anything. One of that
144 + devices is used for managing Broadcom specific core.
145 +
146 +Addresses of AMBA devices are not hardcoded in driver and have to be read from
147 +EPROM.
148 +
149 +In this situation we decided to introduce separated bus. It can contain up to
150 +16 devices identified by Broadcom specific fields: manufacturer, id, revision
151 +and class.
